The Royal Unova is a boat found at the dock by the Pokémon Centre in Castelia City. Until you beat the game, you cannot access this boat. However, once you have received the National Pokédex, you will be able to access it. The Royal Unova sets sail once a day, with it's sailing time varying between season.Spring: 17:00-19:59Summer: 19:00-20:59Autumn: 17:00-19:59Winter: 16:00-18:59 It costs you 1,000 PokéDollars to get on. However, there is a catch. There is a time limit to being on the boat. Once that time limit is passed, the boat redocks at Castelia City and you get given an item based on the trainers you defeated

The Deck

The first bit you'll see are some stairs in which you can climb and get on the deck of the ship. This feature allows you to then watch as the Royal Unova does its journey along the water. It goes under the Sky Arrow Bridge and all the way up to the Marvelous Bridge before looping down and getting back to Castelia City. This feature fully shows off the game's 3D rendering engine

Trainers

In the various rooms of the Royal Unova are numerous characters and trainers. Some will offer you battles, while others will give you a variety of items afterwards. The trainers that battle you will give you a good chunk of money and can be rebattled each day with different ones battling you on different days so be sure to keep coming back.
